Used Hyundai i20 Prices in the UK (2025)

Pricing depends on age, mileage, and condition. Here's what you can expect:

• 2022 Hyundai i20: £10,500–£13,500 (20,000–35,000 miles)
• 2021 Hyundai i20: £8,500–£11,000 (30,000–50,000 miles)
• 2020 Hyundai i20: £7,500–£10,000 (40,000–65,000 miles)
• 2019 Hyundai i20: £6,000–£8,500 (50,000–80,000 miles)
• 2018 Hyundai i20: £4,500–£6,500 (70,000–100,000 miles)

Prices vary by location, specification, and whether the car is supplied by a franchised Hyundai dealer or an independent. A petrol 1.2-litre SE model with around 50,000 miles might cost £7,500–£8,500, while a newer 1.0T turbocharged Premium variant could reach £12,000+.

Trim Levels & Which Offers the Best Value

The i20 is available in several trim levels across different model years. Understanding the differences helps you spot genuine value.

• S (Entry Level): Manual windows, manual mirrors, basic infotainment, air conditioning. Good for budget buyers but limited kit. Not always available on newer stock.
• SE (Mid-Level): Electric windows, electric mirrors, 5-inch touchscreen with Apple CarPlay, DAB radio, and better upholstery. The sweet spot for used buyers—common, well-equipped, and reasonably priced.
• Premium/N Line: Climate control, reversing camera, 8-inch touchscreen, sat-nav, leather steering wheel, alloy wheels, and enhanced safety tech. Worth the extra £1,000–£2,000 if budget allows.

The SE trim remains the best value pick for most buyers. You get modern conveniences without the premium tax that comes with top-spec models. If you can find a 2021–2022 SE with a turbo engine, you've landed an excellent used car.

Engine Options: Petrol vs Turbo

The i20 petrol range has evolved:

• 1.2-litre Petrol (MPI): 84 PS, frugal and reliable. Pre-2020 models mostly came with this. Good for low mileage and city driving but slower on motorways.
• 1.0T EcoBoost Petrol: 100 PS, turbocharged, better performance, similar fuel economy. Introduced around 2020. More responsive and worth seeking out if budget permits.
• 1.2 Petrol (MPi): Found on newer generations (2021+), efficient and familiar engineering.

For a used purchase, the 1.2-litre naturally aspirated engine is proven and low-stress. The 1.0T offers better acceleration and is just as reliable if serviced properly. Both are petrol-only in the UK market—there's no hybrid or electric i20 yet.

Common Issues & What to Check When Viewing

The Hyundai i20 is fundamentally sound, but like any used car, specific concerns apply:

Electrical Glitches

Older i20s (2015–2018) occasionally report infotainment touchscreen lag or unresponsive buttons. Check the 5-inch or 7-inch screen powers up quickly, responds to touches, and Apple CarPlay/Android Auto connect without delay. If it's sluggish, a software update might fix it, but budget for a replacement unit (around £400–£600) if it fails.

Engine Carbon Build-up

Direct injection petrol engines can suffer carbon deposit build-up on valves, especially on short urban journeys. Check for rough idling, hesitation on acceleration, or warning lights. Most servicing can prevent this with quality fuel and regular oil changes. Request the service history to confirm regular intervals were met.

What to Physically Inspect

• Look for even tyre wear; uneven wear suggests suspension or tracking issues.
• Check door seals and rubber trims for perishing or water ingress stains inside.
• Inspect the underside for rust, especially on the suspension components and exhaust.
• Listen for clunks or squeaks during a test drive on bumpy roads.
• Verify all infotainment functions, including heating and air conditioning.
• Check the service record—consistent Hyundai dealer or reputable mechanic stamps add confidence.

Running Costs: Insurance, Fuel & Servicing

The Hyundai i20 is genuinely economical to run.

Insurance Group

The i20 sits in Insurance Group 10–12 (out of 50), making it cheaper to insure than many rivals. A typical 23-year-old driver might pay £350–£500 annually for a used i20 with comprehensive cover. Get a quote before committing to a purchase.

Fuel Economy

Official figures suggest 47–52 mpg combined for the 1.2-litre petrol, with real-world figures around 42–48 mpg depending on driving style. The 1.0T turbo is marginally thirstier at 45–50 mpg combined. A £30 fill-up will stretch to around 350–400 miles.

Servicing & Repairs

Hyundai parts are affordable compared to German equivalents. A basic service (oil, filter, fluid checks) costs £100–£150 at independent garages, £150–£200 at Hyundai dealers. Major services are needed every two years or 20,000 miles, typically costing £200–£300. Annual MOT usually passes without issues if maintained properly.

Why Buy a Used Hyundai i20?

The i20 consistently ranks well in reliability surveys. It's less trendy than a Ford Fiesta but arguably more dependable. Hyundai's extended warranty coverage (5 years or 60,000 miles on used approved vehicles from dealers) provides extra peace of mind that many rivals don't match. For cash buyers, this is less relevant, but dealer-supplied cars often retain that benefit.

The interior feels premium for a supermini: soft-touch plastics, a decent driving position, and good storage. Boot space is 311 litres, easily beating the Corsa's 309 litres and matching the Fiesta's 375 litres.

Frequently Asked Questions

Is the Hyundai i20 reliable?

Yes, the i20 has a strong reliability record. It ranks well in UK ownership surveys and benefits from simple, proven mechanical design. The main vulnerabilities (as covered above) are electrical glitches on early models and carbon build-up on direct injection engines. Regular servicing and thorough pre-purchase inspections mitigate these risks significantly.

What's the best year to buy a used Hyundai i20?

2020 onwards marks a good sweet spot: the generation is modern, incorporates refined electronics, and benefits from Hyundai's improved warranty structure. Expect to pay £8,000–£10,500 for a 2020–2021 model with 40,000–50,000 miles. If budget is tighter, a 2018–2019 with 60,000–80,000 miles remains excellent value at £5,500–£7,000.

Does the i20 hold its value well?

The i20 depreciates steadily but not sharply. A three-year-old example retains around 60% of its original value. This is respectable and reflects its solid reputation and affordable purchase price. You won't make money selling it privately, but you won't lose heavily either.

Can I get a warranty on a used i20 from a dealer?

Most franchised Hyundai dealers offer 12-month warranties on approved used vehicles. Independent dealers vary; always ask before purchase. Some include extended warranty packages (3–5 years available for around £400–£800 depending on mileage). Read the small print: most exclude wear-and-tear items like brake pads and tyres.

What's the difference between a used i20 and rivals like the Corsa or Fiesta?

The Corsa (Vauxhall) is slightly roomier and trendy in design but less reliable than the i20 historically. The Fiesta (Ford) is sportier and has a more extensive dealer network, but costs more to insure and service. The i20 sits between them: practical, economical, reliable, and cheaper to run. It's the sensible choice for drivers prioritising value and dependability over badge prestige.
